It is first seen thrashing about in its cube, trying to get out. It is released during the System Purge during the first wave. It wraps its body around one soldier and squeezes him to death while swallowing another soldier whole, all within a matter of moments.

The second wave of security guards catches a glimpse of the Giant Snake leaving the elevator area with the Dismemberment Goblins. The snake later eats a man who is flung over a railing by one of the Deadites, catching him in its mouth before he hits the ground.
